Pants for dynamic peak performance in the backcountry . The lightweight Patagonia Snowdrifter Bib is designed for dynamic high performance in the backcountry. It combines stretch fabric for good performance on the climb with the best weather protection to keep you comfortably dry no matter where your hunt for powder takes you. The H2No™ Performance Standard fabric is a supple, 3-layer laminate with stretchy, 100 % recycled ripstop polyester that allows free movement, blocks wind and moisture, and withstands tough conditions. A DWR (durable water repellent) impregnation does not allow moisture to penetrate the fabric and makes it more abrasion resistant. The soft polyester knit lining wicks away wetness, increases comfort and glides easily onto the next layer. The upper part of the pants is made from lightweight Doubleweave fabric with 4-way stretch that breathes superbly, wicks away sweat and fits perfectly into the layering system. The sleek design includes an adjustable dropseat, removable suspenders that detach at the front for quick and effortless donning, and side zips for ventilation. Other features include an ergonomic cut at the knees and hips for full mobility, robust edge protection for long-lasting durability and slim gaiters for a tight seal on the boot. Three pockets keep things tidy: two storage pockets on the leg and a chest pocket with zip, an integrated RECCO® reflector for avalanche rescue increases safety.
